RuntimeException:未设置外观根目录

Question

我正试图在另一个包裹的叉子上开发一个实用程序，用于处理Laravel应用程序的数据库模式。

在我的开发中，我想使用测试，因为上一次没有测试。虽然这个包在应用程序中与Laravel6.x完美地集成在一起，但当我尝试测试包时，它却失败了。

<?php

namespace Abkrim\DbSchema\Tests;

use Illuminate\Support\Facades\Config;
use Illuminate\Support\Facades\DB;
use PHPUnit\Framework\TestCase;
use Faker\Factory as Faker;

class DbSchemaTest extends TestCase
{
    /** @test */
    function it_can_access_the_database()
    {
       $faker = Faker::create();

       $user = DB::table('users')->insert([
           'email' => $faker->unique()->email,
           'name' => $faker->unique()->name,
           'password' => $faker->password(10),
           'rememberToken' => $faker->md5
       ]);
    }
}

如果尝试运行测试

vendor/bin/phpunit --filter DbSchemaTest

1) Abkrim\DbSchema\Tests\DbSchemaTest::it_can_access_the_database
RuntimeException: A facade root has not been set.

一种简单的遗忘。要在Laravel之外测试Laravel包，有必要扩展管弦乐团TestCase而不是PHPUnit

正确的代码是

<?php

namespace Abkrim\DbSchema\Tests;

use Abkrim\DbSchema\DbSchema;
use Abkrim\DbSchema\DbSchemaServiceProvider;
use Abkrim\DbSchema\DbSchemaFacade;
use Faker\Factory as Faker;
use Illuminate\Support\Facades\DB;
use Orchestra\Testbench\TestCase;

class DbSchemaTest extends TestCase
{
    protected function getPackageProviders($app)
    {
        return [
            DbSchemaServiceProvider::class
        ];
    }

    protected function getPackageAliases($app)
    {
        return [
            'DbSchema' => DbSchema::class
        ];
    }

    protected function getEnvironmentSetUp($app)
    {
        include_once __DIR__ . '/../database/migrations/create_users_table.php.stub';

        (new \CreateUsersTable)->up();
    }

    /** @test */
    function it_can_access_the_database()
    {
        $faker = Faker::create();
        $mail = 'fake@mail.tld';

        DB::table('users')->insert([
           'email' => $mail,
           'name' => $faker->unique()->name,
           'password' => $faker->password(10),
           'remember_token' => $faker->md5
        ]);

        $user = DB::table('users')->first();

        $this->assertSame($user->email, $mail);
    }
}
